I've recently bought a pair of PMR446 walkie-talkies with some 5–10 km range, operating at 446 MHz. We've happily used them in Sareks Nationalpark in Sweden. Now I'm moving to Canada, where this ...
I am often skiing with some friends, and would love to have some way of communicating. I've seen quite a lot of bluetooth based systems for motorcycles, but not as many for skiing. The ideal syste...
I am considering getting a Garmin InReach device (a device allowing two-way satellite communication via text messages) and I am trying to decipher the hidden costs of the subscription that comes al...
Garmin says about inReach that to have a two-way satellite communication "you need to have a clear view of the sky". And what about cloud cover?.. Say it's winter and 100% overcast with angry cu...
When going into remote areas, it would be great to be able to communicate with the outside world, for emergency purposes or just to be able to call home on long trips. Is it practical for an averag...
We were out on a night hike. A helicopter showed up, by behavior it was search and rescue, looking not too far away from our group. It might have simply been doing training, but if it was a real ...
On a recent camping trip, I was having great difficulty sending messages with a Garmin InReach. I was in a woods with a moderately thick canopy overhead, but next to a small river so I could step o...
Say you are in the middle of a desert where there is lots of sunshine, and you are trying to signal for help with a signal mirror. Either in the distance there is a person, or there is an airplane...
When hiking, I often find myself in areas where cell phone reception is poor or intermittent. Sometimes the signal is not good enough to make a call, but it is still possible to send text messages...
It seems that you can't use an Iridium handset to place an emergency call without a SIM card (which seems to be more a commercial than a technical issue). What I'm wondering is whether an "expired...
I've always been taught to keep a whistle on me in case of emergencies - it makes sense since it's small and lightweight but could really help in an emergency. However, something I've never really...
Similar to the previous question that turned up when I searched on this topic: Is there a standard set of light signals for mountaineers?, but for sound? Repeating sets of 3 blasts is standard fo...
Whistles can be used to signal to group members, however the downside is that other people may think you are having an emergency. Are there any other devices that would allow you to signal with no...
Going skiing with another family next year and looking for two-way radios to use so we can stay in touch. I've used cell phones in the past but that can get awkward (and since we are going to Canad...
Hello, I am looking for a device to be in communications with another person while skiing without having to push a button. Exactly like a cell phone, but since phones don't work up where we ski loo...
When I'm hiking with my friend, some of the time we hike together, but sometimes we hike seperately, and may be some kilometres apart only to meet on the agreed location for the evening. Our next ...
This question is the opposite from this one: What would the consequences of using a US two-way radio (GMRS/FRS) in Europe? I know Europe has their own frequency range for two-way radios (PMR), but ...
When firing a flare gun in the air, what is the risk of accidentally starting a forest or wildland fire? Does the flare go out completely before it touches the ground?
This answer on another question says that there is a risk of causing a forest fire when using a flare. Is there a recommended/safer way to use flares that lessens this risk, in the event that some...
Suppose one is in distress in the wilderness, and is being searched for by planes or helicopters because they thoughtfully told their friends where they were going and when they'd be back. Alternat...
